"We could never have expected it would become such a huge success. Our best engineers were unable to foresee the server capacity to support the players’ demand. Our biggest prediction was 50 times lower than what actually happened. We knew Pokémon was a powerful brand with 20 years of existence and over 200 million fans across the globe, but people told us this game was for kids, that it had no appeal, that people would need to get out of their homes to play. It wasn’t easy, it was a massive bet. Back then, people were already talking about augmented reality, but nobody knew when this technology would be accessible. And then what happened: within two minutes, you could access an augmented reality experience and catch Pokémon in the real world, free of charge. And this game blew up without the need to advertise it."
